Technology & Innovation

Intermittency issues of wind and solar power supply are feared to jeopardize the stability of the U.S. electricity network. To remedy this issue scientist at the Massachusetts Institute of Technology (MIT) have developed an “air-breathing” battery storage that, at the cheapest, run about $100/kWh and functions only in certain locations.

Commissioning is underway at the Bioenergy Carbon Capture and Storage (BECCS) pilot plant at Drax Power Station near Selby in North Yorkshire. The 6-month pilot project was realized at a cost of £400,000, and is meant to capture 1 tonne of CO2 per day.

ABB Ability Ellipse solution will support Ameren Illinois’ multi-million dollar modernization of their power grid in Illinois. The asset performance management software has a “prescriptive approach”, which will allow Ameren to better predict and prevent the failure of mission-critical equipment that delivers electricity to 1.2 million customers.

With the advent of utility-scale energy storage and hybrid power systems, traditional power producers are turning to system integrators to balance multiple generation assets and optimize the energy produced. Wärtsilä’s GEMS software helped ALTEO Group optimise an engine power plant with energy storage in Hungary, and on the Azores the software used a mircogrid form of AI to control and balance wind, solar and diesel gensets.

Additive manufacturing, or 3D printing, has evolved significantly and today develops turbine components that, in most cases, perform better than their conventionally manufactured counterparts. In the energy field, Siemens is aspiring to qualify 200 components for manufacture via 3D printing by 2025.

Operators in the energy sector are struggling to cope with rising threats to the security of their generating assets. Digitalisation helps ensure a save and stable operating environment to allow for flexible dispatch of power units. Wärtsilä solutions build up an active resistance to cyber threats that guarantees electric utilities a steady return on their assets.

Substations in the digital age are increasingly known as “the heart of the power supply system,” connecting parts of the grid that operate at different voltage levels. Siemens’ vision is a largely decarbonized energy system in a “near-to-all electric world”. The technology is already there, but utilities and grid operators still need to fully embrace it.

Siemens has successfully concluded the first phase of its Subsea Power Grid shallow water test in Trondheim, Norway. Working together with Chevron, Equinor, ExxonMobil, and Eni Norge, Siemens is in the final stages of developing a barrier-breaking system to distribute medium-voltage power, using pressure compensated technology.

Siemens has committed to invest up to 600 million Euros at its industrial estate in Berlin Spandau, a future R&D hub. A new world of working and living will be built on an area of 70 hectares to strengthen selected key technologies and innovations. Research will focus on distributed energy, electric vehicles, digitalization, and 3D printing.

Hydrogen, as an energy carrier and feedstock, has gained momentum amid falling cost of wind and solar power. Once mass-produced at very low cost in places like Argentina, Australia, Chile, the Middle East or South Africa, green hydrogen could become a game-changer, the same way LNG linked previously disconnected regional gas markets.

Predix ServiceMax, just launched by GE Digital, is an Asset Service Management (ASM) system designed to increase equipment uptime and improve maintenance outcomes for industry and power plant operators. Combined with performance management, the new offering helps customers transform their maintenance process from a break-fix model to a predictive service model.

French utility ENGIE has deployed a 150 kW/90 kWh energy storage system in Rotterdam that is made up entirely by second-hand batteries from Renault electric vehicles. The E-STOR system, developed by Connected Energy, is supporting the Tennet electricity distribution grid.

A lifecycle upgrade enhances the equipment of a power plant to meet its original running parameters. With a combined cycle upgrade, more power can be produced with the same amount of fuel by applying waste heat recovery steam generators connected to common steam turbine generator sets. According to Wärtsilä Services Manager Markus Åbrant, this particular type of upgrade can trigger as much as 10% higher energy output.

Development of practical fusion power plants has been slow-moving, but now researchers at the Massachusetts Institute of Technology (MIT) have found an innovative solution on how to get rid of excess heat that would cause structural damage to the plant. The new MIT-originated design features secondary magnets and an enlarged exhaust pipe.

Having just launched H2 solution, its new sequential hydrogen combustion system, Ansaldo Energia is now carrying out further tests with the aim of allowing gas turbines to run entire on renewable gas. “The latest H2 solution is already capable to work in an impressive load range, and with still unmatched hydrogen volume percentages,” the Italian manufacturer stated.
